FAQ About Richtek

Q1: What does a linear regulator do?

A: A high gain differential amplifier is used to regulate an active (BJT or MOSFET) pass device (series or shunt) in a linear regulator. It does this by comparing the output voltage to an exact reference voltage and adjusting the pass device to keep the output voltage constant.


Q2: What’s in a linear regulator?

A: An output driver transistor, a reference voltage unit, a feedback resistor, and an error amplifier are the four essential parts of a linear regulator.


Q3: Can a linear regulator sink current?

A: Using a standard linear regulator designed for positive output voltages presents a challenge because it can only source current, not sink it.


Q4: Where to order Richtek linear regulator online?

A: BD Electronics offers many versions of Richtek linear regulators. You can find the components you seek by visiting the BD Electronics website and searching the product category area.
